    2012 LR4 Speaker Replacement

    I know the Logic 7 system became more powerful I think post 2011. if I remember correctly they went from a 14 speaker 480w system pre 2012 and to a 17 speaker (added tweeters to the mid range center speaker in the front and the 2 surround mid ranges in the back) and to an 825w system. I would...

    2011 LR4 HSE oil question

    15 quarts is insane… my guess is he either did an oil change and forgot to drain the oil (weird) or broken oil level sensor causing him to add absurd amounts and most likely bringing him to sell the car because he thought he was burning it. Get an oil analysis to make sure the engine is...

    Persistent misfire under load only

    Was about to hang it up and take it into the shop but decided to swap out cylinder 5 coil and plug before I did. To my surprise that was the answer. However the fuel trims still behave the same but the misfire is completely gone.

    Camshaft regulator failure - advise needed

    I am in aw… I’ve never seen a camshaft snap like this before.

    AC not cooling - B11FF-85 (2E) code

    The module that runs the HVAC system. Tells the AC clutch when to kick in and other things like that. If you were trying to ask where it is I couldn’t tell you.

    ok, after a slight bit of more research the charcoal canister on the discovery is different... and oh is it expensive. but now that i know its different, does anyone know if i should be able to blow down it freely or if it should be sealed off?

    Persistent misfire under load only

    so i dropped the spare tire in my LR4 and found that the pipe going up to the engine is vacuum tight when i blow from the charcoal canister towards the engine. at that point i figured that the rich condition was most likely caused by the smoke test i did and was probably the residue from the...

    AC not cooling - B11FF-85 (2E) code

    I had an issue like this last summer. I had my compressor and condenser replaced and everything. Worked perfect for a couple of months and then this happened. They replaced the HVAC control module and that solved it.

    Persistent misfire under load only

    Returning with a little bit of insight. Yesterday I tested the the purge valve on the D5 by first comparing the resistance on the purge valve of the D5 compared to my LR4 (both use the same Bosch FoMoCo purge valve.) both red within an Ohm of each other. I never disconnected any lines or moved...

    Persistent misfire under load only

    Curious about the supercharge bypass valve. How would I check that? Anyway to check the MAP sensor as well. The pressure fluctuates with acceleration but I’m not sure that’s enough to tell the integrity of the sensor.

    Tested the purge valve and it works just fine. Any more ideas, what would make the entire engine run odd.

    Persistent misfire under load only

    Hey all, sorry for the week late response. I had surgery on Tuesday and have been recovering since. Today was the first day I felt like a human again so we are back to diagnosing! Here are the lambda values at idle and 2000 rpm. You described them in a wavy fashion and that seems like exactly...

    Persistent misfire under load only

    Sorry for taking a bit. I just replaced the rear upper control arms on my LR4 so I’ve been focused on completing that. Finished that all up, drove to the alignment shop to get my car aligned and found out that the rear toe links are completely seized and the shop can’t adjust them… great! (I...

    Persistent misfire under load only

    Ran fuel trims after the whole experience. Ran it up to 2000 rpms and they were cleaning up, pulling I believe negative 16-18% on the STFT with about 23% on the long term on both cylinders. When I did the smoke test through the purge valve in the intake I had the intake duct all duct taped and...

    Persistent misfire under load only

    If the fuel filter is built into the low pressure pump then wouldn’t I have to replace the whole unit or could I clean the filter? Luckily for me this is a D5 which means I should be able to get to the low pressure pump through the cabin without having to drop the whole tank (unibody).

    Persistent misfire under load only

    Would it make the whole engine read rich or would it make just one bank read rich These are the fuel trims I pulled

    Persistent misfire under load only

    i did not, im guessing it is in the low pressure pump? It originally called out an misfire on cylinder 4, replaced everything on cylinder 4 and now it’s saying cylinder 5 and 5. Should I replace cylinder 5? I have all the working spare parts to do it.

    Persistent misfire under load only

    I believe I only have access to O2 sensor #2 on both banks. Should I take a look at the values while the car is warm? Also I looked at the maf values and both of them are in range of each other. I was on the freeway today driving back home, needed to pass someone so I put my foot down and...

    Persistent misfire under load only

    Sorry, just trying to move on this issue, seems to be getting worse daily. I tested the purge valve and it is closed when the car is off. Fuel pressure seemed normal, is there any specific PSI I should be looking for? When I was doing harder pulls it ranged from 2650-2800 psi. Is there any...

    Didn’t notice it till now but it’s starting to run rough at idle, or like you said the bogging down feeling.

    Haven’t gotten much feedback, I’m just going to buy new MAFs for both and return them if it doesn’t fix the issue.

    Persistent misfire under load only

    so I bought a mini smoke machine off of Amazon and taped up each side of the intake duct and Ran the smoke machine in both PCV lines, in the evap/brake booster lines, and finally let it run through the inlet where the purge valve line connects to. I could not see any smoke coming out of...

    Persistent misfire under load only

    so my IID tool will unfortunately not read the voltages of the MAF sensors. What is the best way that I can check and ensure that they are working properly?

    Persistent misfire under load only

    Vacuum leaks are better than fuel issues! I assume the purge valve is working because every time I worked on cylinder 4 (plugs coil and injector) I would undo the fuel thank vaccuum lines and they would suck in a ton of air from being under vacuum so I assume that there is no leaks in that...
